Open your own thread. Provide your Debug Log. I am not sure where you read uncertainty from the wiki.
Settings: 2.0 (!) no 2.1 no nothing -> 2 channels only
Passthrough: AC3 enabled and Dolby Transcoding enabled.

-> see you in your thread. From the log it is 100% clear why you see PCM on the AVR ... cause you configured kodi to do so.

Thanks again fritsch
The Wiki I looked at was https://kodi.wiki/view/HOW-TO:Submit_a_bug_report

As for selecting “Passthrough: AC3 enabled and Dolby Transcoding enabled”, (as shown in the illustration at https://kodi.wiki/view/Settings/System/Audio), I am unable to select Dolby Transcoding as it is missing from my menu.

Not sure whether this is the cause of my problem, or whether I should be making any other changes to my setup, but I have set up a new thread as per your advice.

Quick question, have the recommended shield and kodi settings been removed from the OP? Are they no longer needed? I'm on Omega Beta 3

Think you got the threads confused, and were perhaps looking for the old thread that was previously pinned at top:

This change probably caused this issue

https://github.com/xbmc/xbmc/issues/24950

it's audio related and caused sometime between beta2 and beta3.
